mpas_tools.split_grids.split_grids

mpas_tools.split_grids.split_grids(infile=None, outfile1=None, outfile2=None, nCells=None, nEdges=None, nVertices=None, maxEdges=None, runner=None)[source]

Split two previously merged MPAS non-contiguous meshes together into separate files. Typical usage is:

split_grids(infile='infile.nc', outfile1='outfile1.nc', outfile2='outfile2.nc')

The optional arguments for nCells, nEdges, nVertices, and maxEdges should generally not be required as this information sould have been saved in infiles’s global attribute merge_point when created by mpas_tools.merge_grids.merge_grids().

Parameters:

  • infile (str) – The file name for the mesh to split

  • outfile1 (str) – The file name for the first split mesh

  • outfile2 (str) – The file name for the second split mesh

  • nCells (int, optional) – The number of cells in the first mesh (default: the value specified in infile global attribute merge_point)

  • nEdges (int, optional) – The number of edges in the first mesh (default: the value specified in infile global attribute merge_point

  • nVertices (int, optional) – The number of vertices in the first mesh (default: the value specified in infile global attribute merge_point

  • maxEdges (list[int, int], optional) – A list of the number of max edges (int) in each mesh (default: the value specified in infile global attribute merge_point OR will use infile maxEdges dimension and assume same for both)

  • runner (str, optional) – The command to write into the global history attribute of the outfile
